Working as experts in the field of wastewater and sludge treatment, we counsel and advise national and international customers from companies, municipalities and water and wastewater associations in all scientific aspects of wastewater and sludge treatment, as well as energy and nutrient reuse. Our work includes dimensioning of wastewater treatment plants by calculation and dynamic simulation. We determine calculation data, work out treatment concepts and offer scientific monitoring and recommendations especially for the start-up phase of large-scale wastewater treatment plants. Also we develop new treatment concepts in regard to minimizing energy and resource demand. A special emphasis of our research and development activities is in sludge treatment. Activities range from sludge treatment concepts and optimization of sludge stabilization to determination of dewatering parameters and conditioning agent demand. We also conduct lab-scale dewatering tests, full-scale investigations or concept studies for energy recycling. Recycling of resources (e.g. phosphorus recovery) from sludge and mass flow balances are also important topics.

If you have any questions please contact us isww(at)tu-braunschweig.de

Sludge Treatment
  • Prediction of full-scale dewatering results using thermo-gravimetric measurements
  • Testing and characterization of sewage sludges and determination of relevant parameters
  • Concepts for optimizing operation of all sludge treatment steps (e.g. thickening, digestion, conditioning and dewatering)
  • Testing and evaluation of sludge disintegration methods
  • Scientific monitoring during the start-up phase of sludge digestion plants and balancing of treatment processes
  • Rheological and granulometric analyses for the determination of the dewatering and flow characteristics of sewage sludge
  • Balancing of full-scale sludge digestion plants
Wastewater Treatment
  • All basic lab tests for physical-chemical and biological treatment and degradability of wastewater
  • Concepts, construction and operation of lab-scale and half-scale pilot plants according to special customer requirements
